PSA PAKE: reintroduce psa_pake_primitive_t
If PSA_PAKE_OUTPUT_SIZE takes cipher_suite as a parameter and it is a
structure it can't be a compile-time constant anymore.
Reintroducing psa_pake_primitive_t, because it can be constructed as an
integral type and holds enough information to allow PSA_PAKE_OUTPUT_SIZE
calculating accurate estimates on the output size in compile time.
